Extra Layer Variable Envelope Generators for Tap Delay
The Extra layer implements two types of envelope generators to give you sophisticated control over the onset of the
sound and tap delay effects. Please refer to the diagrams on the page titled ‘aFrame Extra Timbre Envelope Generator’
(p.13)
The first type, Envelope Generator 1 is activated when the parameter XtraD.Tap is set between the 0 and +8.
As the diagrams show, the parameters XtraDcay and XtraHold function in a standard way to change the envelope of the
sound. When relating this to standard ADSR envelope terminology, we might describe XtraHold as the sustain part of the
envelope, and XtraDcay as the release part.
The parameters XtraDelay and XtraD.Tap produce some interesting rhythmic delay effects when adjusted in combination.
To hear these effects clearly, start with the following settings:
Parameter
Value
XtraType
500ms
XtraHold
250ms
XtraDelay
200ms
XtraD.Tap
+0
Striking the drum you will hear one sound at the instant you strike. With these settings you should be able to hear the
longer hold and decay of the sound’s envelope. Now increase XtraD.Tap to +1 and there will be a 200ms delay after the
strike before you hear the sound. This delay of the onset of the generated sound can add an interesting rhythmical effect
when combined with other instrument timbre layers.
Increase the value of XtraD.Tap to +2 and you will hear two distinct sounds. The first occurs at the instant you strike. The
second tap sound is longer in duration because the XtraDcay and XtraHold envelope values are applied to the second
tap sound. Keep increasing the value of XtraD.Tap up to +8 and you will hear the increased number of taps and also a
rhythmic pattern change. In each case, the last tap sound has the envelope set by XtraDcay and XtraHold.
The second envelope type, Envelope Generator 2, is activated when the value of XtraD.Tap is adjusted in the range -1
to -3000
This also activates additional parameters used to control this envelope type.
